We're dividing 78278742 by 428 
Let's see how many times 428 fits into 78278742.

On to step 1:
428 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 428

Going ahead to step 2:
The number 428 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 428

Step 3:
782 divided by 428 is 1 with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 428 away from 782, we end up with 354.
Append the next digit (7) from the dividend to 354 and continue with: 3547 / 428

Advancing to step 4:
428 goes into 3547 8 times with a remainder of 123.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 123 after subtracting 3424 from 3547.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 428

Step 5:
428 goes into 1238 2 times with a remainder of 382.
Use 2 as the next digit of our solution. 
Result so far: 182.0
The remainder is 382 after subtracting 856 from 1238.
Fetch the next digit (7) from the dividend, attach it to 382 and continue: 3827 / 428

Going ahead to step 6:
If we divide 3827 by 428, we get 8 and a remainder of 403.
Write down 8 as next digit of the result. 
Result so far: 1828.0
Subtracting 3424 from 3827 leaves us with 403.
Fetch the next digit (4) from the dividend, attach it to 403 and continue: 4034 / 428

Let's proceed to step 7:
428 can be fit into 4034 9 times, resulting in a remainder of 182.
Write down 9 as next digit of the result. 
Result so far: 18289.0
The remainder is 182 after subtracting 3852 from 4034.
Grab the next digit (2) from the dividend, add it to 182, then carry on: 1822 / 428

Advancing to step 8:
The number 428 fits into 1822 4 times, leaving a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 182894.0
Subtract 1712 from 1822 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
428 goes into 1100 2 times with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 182894.2
The remainder is 244 after subtracting 856 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 10:
2440 divided by 428 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 182894.25
Subtracting 2140 from 2440 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
3000 divided by 428 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 182894.257
Subtract 2996 from 3000 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
428 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 182894.257
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
428 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 182894.257
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 182894.257 with a remaining 0.0004.
